Descriptions

In the Linux kernel, the following vulnerability has been resolved: cgroup: Add missing cpus_read_lock() to cgroup_attach_task_all() syzbot is hitting percpu_rwsem_assert_held(&cpu_hotplug_lock) warning at
cpuset_attach() [1], for commit 4f7e7236435ca0ab ("cgroup: Fix
threadgroup_rwsem <-> cpus_read_lock() deadlock") missed that
cpuset_attach() is also called from cgroup_attach_task_all().
Add cpus_read_lock() like what cgroup_procs_write_start() does.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: cgroup: agregue cpus_read_lock() faltante a cgroup_attach_task_all() syzbot está presionando la advertencia percpu_rwsem_assert_held(&amp;cpu_hotplug_lock) en cpuset_attach() [1], para el commit 4f7e7236435ca0ab ("cgroup: Fix threadgroup_rwsem &lt;- &gt; cpus_read_lock() deadlock") se perdió que cpuset_attach() también se llama desde cgroup_attach_task_all(). Agregue cpus_read_lock() como lo hace cgroup_procs_write_start().
